Penrithtown, Eden district, administrative county of Cumbria, historic county of Cumberland, northwestern England. It is situated on a main route to Scotland, at the foot of the 937-foot (286-metre) Penrith Beacon overlooking the mountains of the scenic Lake District.

Penrith Castle was built in the 14th century as a defense against the Scottish raids and was dismantled during the mid-17th-century English Civil Wars. The parish church of St. Andrew, of Norman foundation, has a 13th-century tower, but the body of the building is 18th-century.

The town, on the edge of the Lake District National Park, is now a tourist and agricultural centre with a weekly livestock market. Places of interest include the Giant’s Grave and Giant’s Thumb (graves marked by pre-Norman cross shafts) in the churchyard and the Gloucester Arms (associated with Richard III of England [reigned 1483–85]). The ruins of Brougham Castle, with a 12th-century keep, stand on the site of a Roman fort 1.5 miles (2.5 km) to the southeast. Pop. (2001) 11,988; (2011) 12,549.
